PATENT SIMON ROSS, OF CINCINNATI, OHIO.

SPECIFICATION forming part of Letters Patent No. 47' 2,399, dated April 5, 1892.

Application filed November 18, 1891. Serial No. 412,290. (No model.)

To all whom it may concern.-

Be it known that I, SIMON Ross, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Sole-Trimming Machines, of which the following is a specification.

One of the objects of my invention is to produce a machine that will trim or shape from what is known as blocked stock a sole or tap to any predetermined size from a given pattern.

Another object of my invention is to clamp the stock and pattern together and arrange them in close relation with a pattern-guide supported in juxtaposition to the cutter, thereby preventing variation of the sole from the pattern, due to lateral strain or lost motion.

Another object of my inventionis to provide a revoluble clamp and pattern mounted upon a shaft, which is turned and presented to the cutter by the operator, who varies the feed as the need of the box requires.

Another object of my invention is to mount the guide on a shifting slide, so it can be adjusted to the different sizes required by means of an adj usting-screw, and a lever can be made use of when the amount of material is great enough to require two cuts.

The various features of my invention are fully set forth in the description of the accompanying drawings, making a part of this specification, in which- Figure 1 is a side elevation of my improved sole trimming or shaping machine. Fig. 2 is a front elevation of the main frame and cutter. Fig. 3 is a front elevation of the jackframe. Fig. 4 is an enlarged top plan view, partly in section, of the cutter -head and clamping device. Fig. 5 is an enlarged sectional elevation of the cutter-head and guide. Fig. 6 is a plan View of the pattern and spacing-plate; Fig. 7 is a section on line as, Fig. 4. Fig. 8 is a sectional detail view. Fig. 9 is a perspective of the fence.

1 represents the bed-plate of the machine; 2, the main frame mounted thereon.

3 represents a blower; 4., a dust-tube.

represents the main driving-shaft; 6, the main driving-pulley. This main driving-pulley transmits power to pulleys 7 on the cutter-shaft 8.

9 represents a second pulley, mounted on the main shaft 5 and transmitting power by the belt 10 to the pulley on the blower-shaft 11.

A represents the cutter-head, mounted on shaft 8. The knives or bits may be of any well-known form of construction.

B represents a jack-frame, provided with a sleeve 12, that journals on stud-shaft 13. (See Fig. 2.)

14 represents a driving-pulley on the main shaft 5, and 15 represents a loose pulley on the same shaft.

16 represents a table, on the bracket of which is loosely mounted a stud-shaft 17, so as to be capable of oscillating in its bearing. 0 represents a fence journaling on said shaft and provided with the guide 18.

19 represents a set-screw for adjusting the fence laterally on the stud 17.

. .20 represents a stud-shaft, on which the shank 21 of the guide 18 slides. Its adjustment is regulated by the set-screw 22.

23 represents a weight attached to a chain passing over the sheave 24., one end of said chain 25 being secured to the Weight 23 and the other end secured to the jack-frame. The Weight normally draws the jack-frame forward to the cutter-shaft. It is held back by means of the catch-lever 2.6, the end of which engages on the stud 27 on the jack-frame.

D represents a grooved guide, which journals in the sleeve 28. 29 represents a slide supporting said sleeve and gained into a guideboX 30.

31 represents a set-screw for adjusting the slide 29 to carry the guide D forward and backward for adjusting it to different sizes of work required.

a I) represent collars on the shank of the screw 31 to limit the forward and backward movement of the slide 29. It may be desired to throw this guide forward at times in order to reduce the extent of cut when it is required to make two outs instead of one in reducing the stock. This is accomplished by moving the shipping-lever 33 so as to spring the catch 34: in engagement with the lug 35, and thus hold the guide in its most advanced position. When too the shipping-lever is moved backward, the slide 20 is free to move backward.

E E represent clamping-heads. The clamp E is mounted upon the stud-shaft F and the clamp E is mounted upon the gudgeon II of a screw-shaft G. The shaft G is screw-threaded through a split box I, supported upon the fork J of the jack-frame B.

K represents a sleeve supported on the fork L. This sleeve is screw-threaded through the boxing M, so that said sleeve may be adj usted longitudinally.

N represents a hand wheel secured to shaft F.

0 represents a handle secured to the rim of the wheel and may be operated to turn the said shaft and revolve the clamp-heads E E.

It represents a spacing-plate provided with holes '2' s to pass over dowel-pins projecting from the clamping-head E. P represents a pattern provided with similar holes and placed between the spacing-plate R and the clamping-head E.

S represents stock clamped by the clampin g-heads E E. This construction enables the clamping-heads E E to be used for various sizes of work, but the clamping-heads maybe changed, if desired, as they are readily detachable from their supporting-gudgeons. The clamping-heads are driven by the hand-wheel N, which is turned by the operator to present the stock to the action of the cutter. Important advantages are obtained by this means, as the operator can turn the clamping-heads fast or slow, presenting the stock to the cutter no faster than it will reduce it. Thus if stock for the soles of a childs shoe is being reduced there is much less stock to be cut away, and it can be revolved faster; but if a large sizesay the sole of a mans shoeis to be reduced there is much more stock to be reduced, and it must travel a longer distance during the revolution and much more stock is taken off by the cutter, and a slower motion is required to avoid overfeeding. Another important advantage is obtained by arranging and clam ping the pattern close up to the stock to be reduced and the guide close to the cutter-head, and having the pattern and clamp supported on one and the same shaft and close together, as an accurate feed of successive charges of stock may be obtained, and they are trimmed to the exact size of the pattern P, which travels in the groove of the guide D, the guide being close to the cutter-head and the stock close to the pattern.

In Fig. 5 I have shown the guideD recessed out, so as to span the screw-head t, which clamps the cutters on the shaft 8. In order that the guide D may be readily moved out of the Way to take off the eutter-head,I mount the guide-box 30 on the shaft 36, where it is held in position by the clamping-box 37, and 38 represents a clamping-screw, which is loosened to allow the said guide-box to be turned up or down, removing the guide out of the path of the cutter-head. In order to set the screw-shaft G in a fixed position, it passes through the split box I, where it is secured in posit ion by set-screw 3!), so that said shaft G may be turned to clamp the heads E E and then set by the screw 39 to hold it in a fixed position. The clamping-head E forms the base on which the patternPrests, and it must be adjusted exactly to the groove in guideD. This adjustment is secured by turning the sleeve K in box M, so as to move the clamping-head E and the pattern laterally to secure the alignment. The spacing-plate R keeps the pattern P a sutiicient distance away from the cutter to prevent the pattern from interfering with the action of the cutter and allowing the inner edge of the stock to be completely trimmed down.

Having described my invention, what I claim is 1.
